Stability and Reliability of Repeated Plasma Pregnenolone Levels After Oral Pregnenolone Dosing in Individuals with Cocaine Use Disorder: Pilot Findings.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Substance use disorders (SUDs), including cocaine use disorder (CUD), have significant negative health risks and impose a substantial social burden, yet effective treatments are limited. Pregnenolone, a neuroactive steroid precursor, has been shown to reduce alcohol craving and normalize stress biology in individuals with CUD, but its clinical utility has been questioned due to limited data on bioavailability and the stability of blood levels in humans. Thus, this pilot study aimed to determine whether twice-daily oral pregnenolone (PREG) at 300 mg/day and 500 mg/day versus placebo in week two of PREG administration led to stable increased plasma pregnenolone levels in individuals with CUD. Seven treatment-seeking individuals with CUD, enrolled in an eight-week double-blind clinical trial, were randomized to receive placebo (
